Treatment with KOH increased the number of surface functional groups and tetracycline adsorption at 300 °C, whereas it decreased that 500 700 °C.
The structures of the crosslinks in supramolecular polymer networks play an important role on their properties and functions. Herein, emissive metallacages are used as to prepare metallacage-cored polyurethanes. mechanical including storage modulus, toughness, Young's modulus breaking strength polymers greatly enhanced with increase crosslinking densities. Moreover, such not only exhibit good fluorescence solid state, but also show self-healing shape memory owing dynamic reversible...
Abstract Two coordinated metallacycles (rhomboid for M1 , hexagonal M2 ) with selenoviologens (SeV 2+ pendants were synthesized via coordination‐driven hierarchical self‐assembly. / rigid and discrete metallacyclic cores showed tunable optoelectronic properties due to strong π–π stacking push–pull electron structures. Femtosecond transient absorption (fs‐TA) revealed that the formation of macrocyclic structure can not only enhance stability radical cation, but also improve efficiency...
A microcosm experiment was conducted for 112 d by spiking petroleum hydrocarbons into soils from four regions of China. Molecular analyses microcosms revealed changes in taxonomic diversity and oil catabolic genes microbial communities. Degradation total (TPHs) Sand the Bohai Sea (SS) Northeast China (NE) exhibited greater mineralization than those Dagang Oilfield (DG) Xiamen (XM). High-throughput sequencing denaturing gradient gel electrophoresis (DGGE) profiles demonstrated an obvious...
Emulsification is one of the important processes in chemical flooding to mobilize residual oil wells following secondary recovery. Oil displacement efficiency enhanced and volumetric sweep increased by engineering interactions supporting chemicals used with geological formations present wells. Polymers surfactants are often applied recovery (EOR) as emulsification displacement. However, polymers limited poor temperature salt tolerance, while have a high cost. In this contribution, we report...
Highly emissive metallacages that generate reactive oxygen species (ROS) are important to synergistic cancer therapy, but it is still challenging balance the emission and phototheranostic properties. Herein, a metallacage of DTPABT-Mc prepared. It observed in near-infrared region from 600 1000 nm with high photoluminescence quantum yield value 7.92% solids recorded for DTPABT-Mc. In addition, ability produce both type I II ROS under light irradiation also observed, leading potential...
A stable emulsion can play an important role in displacing oil or controlling reservoir conformance for enhanced recovery (EOR) projects. In this work, visual inspection, multiple-light scattering, interfacial tension (IFT), and rheology were used to investigate the synergistic effects of regenerated cellulose surfactant on oil-in-water emulsions stability their efficiency EOR. The results show that adding significantly increase a emulsion, while decreasing diameter, coalescence, floatation...
In this study, we investigated an alternative to the conventional hydrochloric acid leaching of roasted bastnaesite. The studies suggested that rare earth oxyfluorides in non-oxidatively bastnaesite can be selectively leached only at elevated temperatures Further, Ce(IV) oxidatively does not leach readily low temperatures, and it is difficult induce form a complex with F- ions order increase efficiency. Moreover, inevitably reduced Ce(III) temperatures. Thus, ultrasonically-assisted was...
Abstract The design of novel materials for sulfur dioxide (SO 2 ) capture and conversion with considerable efficiency under mild conditions is great significance human health environmental protection yet highly challenging. Herein, we report a series triazine‐based multicomponent metallacages via coordination‐driven self‐assembly 2,4,6‐tri(4‐pyridyl)‐1,3,5‐triazine, cis‐Pt(PEt 3 (OTf) different tetracarboxylic ligands. As the increase length tetracarboxylates, structures change from pyramids...
The effects of particle size, temperature, and leaching time on the behavior rare-earth elements were studied. efficiency rare earth reached 39.24% under conditions hydrochloric acid concentration 8.00 mol/L, size 95% distributed below 1.5 μm, 120 min, temperature 90 °C. According to scanning electron microscopy X-ray diffraction analysis residue, mechanism process was also investigated. Actually, phase REFCO3 transformed into that RECl3 REF3 but there an existing intermediate transition,...
Control over the adhesive properties are of great importance for both biological and chemical systems. Herein, we use amino‑yne click reaction to prepare metallacycle-crosslinked supramolecular polymer networks, which further employed as reversible materials. The introduction metallacyclic structures not only gives formed networks good emission self-healing properties, but also affords improved adhesion strength increased glass transition temperature, making them serve emissive adhesives....
To improve the efficiency of mobility control for polymer flooding, a novel thickening system was formed by adding medium-chain fatty alcohols to hydrophobically modified polyacrylamide (HMPAM) brine solutions. The interaction HMPAM with investigated in terms rheology properties, aggregate microstructure, and ability. results show that n-octanol (C8OH) generates best synergistic behavior compared other alcohols. More hydrophobic groups initially existing either intramolecular or...
